[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Specific examples are given below.

[0032] See also Figure 1 - Figure 7The present invention provides a charging cable protection device for a charging pile and a method of using the same, comprising a cable body 14, a cable fixing assembly and a cable cleaning assembly; the cable body 14 is wound and fixed in the middle of a take-up wheel 13; a fixing column 12 is connected to a torsion spring in the middle of the take-up wheel 13; the fixing column 12 is fixedly connected to the inner wall of a charging pile housing 1; a charging gun 15 is fixedly connected to the end of the cable body 14; a cable fixing assembly is fixedly connected to the inner wall of the charging pile housing 1; a cable cleaning assembly is fixedly connected to the side wall of the charging pile housing 1; a display 11 is fixedly connected to the charging pile housing 1. During operation, as the number of new energy vehicles gradually increases, a large number of supporting equipment has also been built in cities to facilitate energy replenishment for new energy vehicles, and most of the charging piles are outdoors, so that the cable body 14 is located outside all year round and is blown by the wind. The cable body 14 is exposed to rain, thereby affecting the service life of the cable body 14. Through the protective device, when the charging pile is not in use, the cable body 14 is stored in the charging pile housing 1 by the take-up wheel 13, and the fixed column 12 is connected to the take-up wheel 13 by a torsion spring. When the charging gun 15 is used, the user pulls out the cable body 14, and the torsion spring pulls the cable body 14 back when not in use, thereby effectively reducing the situation where the cable body 14 is exposed to the outside for a long time, thereby reducing the aging of the cable body 14, thereby achieving the effect of protecting the cable body 14. By storing the cable body 14 in the charging pile housing 1, the situation where the cable body 14 is pressed by the vehicle is reduced, and the situation where the cable body 14 is exposed to the outside is further reduced, thereby reducing the occurrence of external accidents, thereby effectively increasing the service life of the equipment.

[0033] Further, such as Figure 2 - Figure 7 As shown, the cable cleaning assembly includes a cleaning tube 2, a flexible valve 21 and a sponge ring 22; the cable body 14 passes through the cleaning tube 2; the flexible valve 21 is fixedly connected to the middle of the cleaning tube 2; the sponge ring 22 is fixedly connected to the middle of the cleaning tube 2; the cable body 14 passes through the flexible valve 21 and the sponge ring 22. During operation, after the cable body 14 is stored in the take-up wheel 13, since the cable body 14 is in the outside during the use of the equipment, the rain outside accompanied by the mud on the ground will adhere to the surface of the cable body 14 on rainy days. Through the set flexible valve 21, when the cable body 14 is pulled back into the charging pile housing 1, the flexible valve 21 will scrape off the mud and impurities on the surface of the cable body 14, and then when the cable body 14 passes through the sponge ring 22, the sponge ring 22 will absorb the moisture on the surface of the cable body 14, so that the surface of the retracted cable body 14 is clean, and the cleaning assembly is set to effectively clean the surface of the cable body 14, thereby reducing the corrosion of the surface of the cable body 14, thereby increasing the service life of the equipment.

[0034] Further, such as Figure 2 - Figure 7 As shown, the cable fixing assembly includes an electric push rod 3, an extrusion plate 31 and a fixing block 32; the inner side wall of the charging pile shell 1 is fixedly connected to the electric push rod 3; the output section of the electric push rod 3 is fixedly connected to the extrusion plate 31; the side wall of the cleaning tube 2 is fixedly connected to the fixing block 32. During operation, after the cable body 14 is pulled out, the torsion spring between the take-up wheel 13 and the fixing column 12 will generate a reaction force to pull the cable body 14 back. Through the cable fixing device set, after the cable body 14 is pulled out, the electric push rod 3 will drive the extrusion plate 31 to fix the cable body 14 between the fixing block 32 and the extrusion plate 31, and then clamp the cable body 14 between the extrusion plate 31 and the fixing block 32, so as to fix the cable body 14, so that the cable body 14 will not be pulled back into the charging pile shell 1, thereby facilitating the use of the equipment by the staff.

[0035] Further, such as Figure 2 - Figure 7 As shown, a fixing frame 4 is provided on the inner wall of the charging pile housing 1; the fixing frame 4 is fixedly connected to the inner wall of the charging pile housing 1; a roller 41 is provided in the middle of the fixing frame 4; the roller 41 is rotatably connected to the middle of the fixing frame 4; an arc groove 42 is provided on the side wall of the roller 41. During operation, when the user needs to charge, after taking out the charging gun 15 and pulling out the cable body 14, the cable body 14 can be bent to a certain extent inside the charging pile housing 1 through the provided roller 41, thereby effectively facilitating the pulling out of the cable body 14 and reducing the cable body 14 from hanging on the corners of the cleaning tube 2 when being pulled out, thereby effectively reducing the situation where the surface of the cable body 14 is scratched, thereby effectively improving the service life of the equipment.

[0036] Further, such as Figure 2 - Figure 7 As shown, a top cover 51 is provided on the top of the charging pile housing 1; the top cover 51 is fixedly connected to the top of the charging pile housing 1; a charging gun protection cover 5 is provided on the side wall of the charging pile housing 1; the charging gun protection cover 5 is fixedly connected to the side wall of the charging pile housing 1. When working, the charging gun 15 can be effectively protected by the provided charging gun protection cover 5. When the charging gun 15 is not in use, the rainwater is reduced from entering the metal electric contact part at the end of the charging gun 15, thereby effectively increasing the protection effect of the equipment. The provided top cover 51 can effectively reduce the adhesion of rainwater on the surface of the charging pile housing 1, thereby effectively reducing the situation where rainwater enters the inside of the charging pile housing 1.

[0037] Further, such as Figure 2 - Figure 7As shown, a drainage hole 6 is provided on the side wall of the cleaning tube 2; the drainage hole 6 is arranged at an angle. During operation, when the cable body 14 is stored in the take-up wheel 13, rainwater from the outside will adhere to the surface of the cable body 14, and through the drainage hole 6, the rainwater will be collected by the flexible valve 21 and the sponge ring 22 inside the cleaning tube 2, and then discharged from the drainage hole 6, thereby reducing the situation where rainwater remains in the cleaning tube 2.

[0038] Further, such as Figure 2 - Figure 7 As shown, a rubber pad 7 is provided at the end of the extrusion plate 31; the rubber pad 7 is fixedly connected to the end of the extrusion plate 31. During operation, through the rubber pad 7 provided at the end of the extrusion plate 31, i.e., the surface in contact with the cable body 14, when the electric push rod 3 drives the extrusion plate 31 to fix the cable body 14 between the fixing block 32 and the extrusion plate 31, the rubber pad 7 can effectively increase the friction force of the device on the cable body 14, thereby effectively improving the fixing effect of the device, and at the same time providing certain protection for the cable body 14.

After the cable body 14 is stored in the take-up wheel 13, since the cable body 14 is in the outside during the use of the equipment, the rain from the outside and the mud on the ground will adhere to the surface of the cable body 14 on rainy days. Through the flexible valve 21, when the cable body 14 is pulled back into the charging pile housing 1, the flexible valve 21 will scrape off the mud on the surface of the cable body 14, and then when the cable body 14 passes through the sponge ring 22, the sponge ring 22 will pull the cable The moisture on the surface of the main body 14 is absorbed, so that the surface of the retracted cable body 14 is clean. The cleaning component is provided to effectively clean the surface of the cable body 14, thereby reducing the corrosion of the surface of the cable body 14, thereby increasing the service life of the equipment. After the cable body 14 is pulled out, the torsion spring between the take-up wheel 13 and the fixing column 12 will generate a reaction force to pull the cable body 14 back. Through the cable fixing device provided, after the cable body 14 is pulled out, the electric push rod 3 will drive the extrusion plate 31 to fix the cable body 14 between the fixing block 32 and the extrusion plate 31, and then clamp the cable body 14 between the extrusion plate 31 and the fixing block 32, so as to fix the cable body 14, so that the cable body 14 It will not be pulled back into the charging pile housing 1, which is convenient for the staff to use the equipment. When the user needs to charge, after taking out the charging gun 15 and pulling out the cable body 14, the cable body 14 can be bent to a certain extent inside the charging pile housing 1 through the provided roller 41, which effectively facilitates the pulling out of the cable body 14 and reduces the cable body 14 hanging on the corners of the cleaning tube 2 when being pulled out, thereby effectively reducing the situation where the surface of the cable body 14 is scratched, thereby effectively improving the service life of the equipment. The provided charging gun protective cover 5 can effectively protect the charging gun 15. When the charging gun 15 is not in use, it reduces rainwater from entering the metal electric contact part at the end of the charging gun 15, thereby effectively increasing the protection effect of the equipment.The top cover 51 can effectively reduce the adhesion of rainwater on the surface of the charging pile housing 1, thereby effectively reducing the situation where rainwater enters the interior of the charging pile housing 1.

Through the drainage hole 6, the rainwater will be collected by the flexible valve 21 and the sponge ring 22 inside the cleaning tube 2, and then discharged from the drainage hole 6, thereby reducing the situation where rainwater remains in the cleaning tube 2. The rubber pad 7 is set at the end of the extrusion plate 31, that is, the surface in contact with the cable body 14. When the electric push rod 3 drives the extrusion plate 31 to fix the cable body 14 between the fixing block 32 and the extrusion plate 31, the rubber pad 7 can effectively increase the friction of the device on the cable body 14, thereby effectively improving the fixing effect of the device, and at the same time, the cable body 14 is protected to a certain extent.
